Figure 49 is a detail fragmentary figure to disclose parts not appearing in the preceding figures.

In Figures 1, 3 and 4 the frame A is provided with a hollow horizontal shaft A. The outer end of this shaft A is provided with a lug having a hole in the center for the purpose of supporting and fastening the mechanism inside of the cabinet. There are three other similar supports shown in Figure 10.

On the shaft A is mounted a revolving wheeltype magazine B. Abutting the end of the hub B of this magazine, which hub is bored to fit the hollow shaft A azine to be easily rotated, there is a collar a (see Figure 2) securely fastened on the shaft A by a set screw (shown but not numberedfiso as to prevent the hub B of the magazine from slipping out of place. On the back end of the hub B are milled four keyways 11 shown in Figs. 10 and 11.

On this hub is mounted a cam B (Figures 2 and 8), and four' ratchet wheels B B, B and B, the teeth of the ratchet wheel 13 facing reversely to the teeth of the other ratchet wheels, and all are keyed conventionally in keyways b of the said hub, and spaced apart and from the cam by collars (not numbered), on the hub. Four brackets IG, 2G, 8G and 9G are associated with ratchet wheels 13'', B B and 3 respectively and are equipped respectively with spring-actuated dogs or pawls I H, 2H, 8H and 9H for engagement with ratchet wheels B", B B and B respectively. The dogs or pawls I H, 8H, and 9H and the associated ratchet Wheels are disposed for effecting counterclockwise movement of the magazine, and the dog or pawl 2H and ratchet wheel B for effecting clockwise movement of said magazine.

These four brackets are each composed of two spaced plates each having three lugs on-each plate and are held the proper distance apart by means of shoulder rivets, the respective spring actuated with the notches as shown in Figs. and 11'.

The ratchet bracket 2G (see Figures 33 and 34) is slightly different from the other three and works in the reverse way. In this bracket I have provided a knuckle 2E which has trunnions adapted to hinge in the holes bored for that purpose in the brackets 2G. This knuckle has also a small hole' bored through it to permit it to slide on the small end I of the rod 2F. There is also provided a shoulder rivet in the upper lug of said bracket, which, together with the other two shoulder rivets, hold the two plates the proper distance apart.

The upper shoulder rivet is also used for the purpose of attaching a. spring 2D. Figure 10 shows this bracket in position with the front plate removed, and the spring actuated dog 2H is provided with a tail h. In this view I have shown a plate A6 with a narrow project-ion or arm a6. On the other end of the plate A6 I have provisions for supporting a spring [-1. When the spring 2-1 causes'the bracket 2G to be pulled back to its limit, the tail on the spring actuated dog 2H comes in contact with the arm a6, causing the dog 2H to be raised up clear of the ratchet plate B5, permitting the revolving magazine to be rotated as'required.

so that it will permit the mag- There is acam lever 2A, pivoted to a connecting rod'2F which is diametrically reduced (Figure 8) enough on one end to permit it td pass through the hinged knuckle 2E, which .is hinged in the upper portion of the bracket 2G as explained. In the intermediate portion of this rod 2F isa lug ,f to which one end of the spring 2D is attached. The other 'end of this spring is hooked on a shoulder rivet which holds the upper lugs of the brackets 2G in position. In Fig. 10 this plate is shown removed, so as to show the reverse ratchet action. On the small end of the rod 2F a spring 2 1 is attached. The other end of this spring is hooked to the. frame arm A6. As the backing up motion of the bracket 2G is only permitted to travel as fast as the declines on the cams l and 8 (Figure 20) will permit, and in view of the fact that the declines may not be at all times exactly in time with the backing up cam 2, (Figures 12 and 16), the spring 2D will yield, allowing the knuckle joint 2E-to slip on the small end of the rod 2F but it will keep sufficient pressure against the receding cams to cause a steady backing up motion.

The backing up cam 2 (see Figures 12, 16, 1'7 and 10) is so cut as to be just a little in the lead of the receding cams I, 8 and 9 (see Figures 12, 16, 1'7, 18, 19 and 20).

Journaled in the projection 11-13 of the frame A, shown in Figures 1, 3 and 13, is a shaft 4J. On the upper end-of the shaft U is secured a lever 4K with a roller is at the end thereof. This roller is at the proper time comes incontact with the leversor tails c2 of the plates C2 and causes the partial rotation of the shafts Ci journaled in plates C4 and;provides the means for swinging the record support D in position over the turntable, see'Fig. 28. The drawings show twelve of said journal plates carried by and arranged in a circular series around the revolving magazine, one for each record.

On the lower end of shaft IJ is an arm 4G having an oppositely projecting arm or tail 4H (see Figure 14) the rear end of 4H is a spring 4-1 which is attached at the opposite end to a suitable hook-4--i-on the frame A (see Figure 2). The purpose of thisspring is to cause the shaft J to rotate backwards to its normal position when the pressure is released on the camlever 4A (see Figure 13). Cam lever A operated by cam 4 on shaft L, is connected by means of a knuckle joint to connecting rod 4F which is securely fastened to the forward end'of arm (3 of shaft lJ.

At the right-hand end of frame A is provided a housing I (see Figures 1 and 7), for the vertical worm shaft Fand .intermeshing worm wheel Fl (see Figures 5 and 7). At the front and lower portion of this housing a projection has been 6 turned to fit the'collar- |0l of a suitable motor sup- .mounted loosely on the shaft is a sleeve J Worm threads have been cut on the periphery of the sleeve J which engage the teeth of. the worm wheel ,Jl (Figure '7). On one end of this sleeve is larger and has fourkeyways I03 cut in it. Mounted on this portion of the shaft, so as to slide but not turn, is a spring actuated clutch H, shown in Figs.- 5 and 6. In one end of this clutch is provided a loose piece H2 twith clutch notches 11.2.

This'portion H2,has been broached to leave four keys I04 that fit in the keyways I03 in drive shaft There is a collar H6 screwed on the threaded portion of H2. .The threaded collar H3 is provided with left hand threads and a shoulder flange. The part H of the clutch, is threaded to 1 receive and fit the collar H3 as shown in the drawing, Fig. 6. There is a shifting yoke H4 (Figures. 6 and 7) with trunnions M to fit the upper slots in a pivoted fork K (Figures 1, 5 and The clutch jaws h2 and J2 are cut slightly hooking, with the extreme points beveled at about '45 degrees bevel. The object of these beveled I points is in case the point of one jaw should catch and the other jaw should come in contact with the top of the opposite clutch, it would fail to either go in, or slip, to prevent it from jamming. With the beveled jaw, in case they do not both enter past the bevel, the part H2 will be crowded back, compressing the spring H5, allowing it to slip out and then be forced back quickly within the next revolution.

In the larger portion of this shaft F2 there is milled a multiple worm thread F6 as shown in Fig. 5. I have provided a small turn-table G (Figure 1') fastened securely on a shaft GI (Figure 5) and upon the shaft GI is secured a worm- F6 on the shaftFZ.

The fork K is grooved or slotted on the upper portion thereof on either side to support the shifting yoke H4 and permit it to turn. There are two lugs provided in the lower portion with holes to fit the bolt K2. One of these lugs which extends wheel F3 which meshes with the multiple worm down is curved to contact with cam I. (Fi ure 1.)

It also has an additional projection for the pur.-

pose of attaching a spring k3 as shown in Fig. 1. In the frame A, are suitable holes bored for bearings for the fork K. The bushing Kl' (Figure 7 isplaced through theseholes. The shifter'fork K is slipped down over on the outside of the frame member and the bolt K2 is passed through the holes with its nut clamped against the ends of the bushing KI, and thus the bushing Kl becomes the journal for the shifter fork K, as shown in Fig. 7. I have provided alever R pivoted at its center by shoulder screw 1' to a projection rl (Figure 4) on the frame A. On one end of this lever B, I

On the opposite end is provided a suitable '7, during the playing of a record. The latch piece 1 R3 is fastened to rock-shaft R4, mounted in suitable bearings 14 in the frame A, see Figures 2 and 4 On the opposite end of the rock-shaft R4 I have provided atrip R5 (Figure 7). The trip R5 is provided with a hole'adapted to fit the ends of J is a flange or collar which 'engaging the housing; the shaft against the shouldered portion and riv prevents endwise movement of the sleeve. On the other end it has two clutch jaws J2, shown in Figs. 1 and 5. The middle portion of drive shaft F2 eted thereon, 'so' that the trip R5 is rigidly fastened'on the rock-shaftRl. The trip R5 is for the purpose of trippin the mechanism when the recany time that the notches in the peripheral edge of plate S come in contact with the trip R5 in a backward motion it causes the shaft to rock and the latch key R3 releases the lever'R permitting it to drop down and back of the spiral HI on the clutch H. With a single revolution of the shaft F2, the clutch H is crowded endwise until the clutches 71.2 are engaged in the clutches J2. This causes the worm sleeve J to rotate with the drive shaft F2. The adjustable stop It! is used for the purpose of tripping when playing a record that has a spiral groove and used for a stop on other records thatave a uniform stopping place, see Fi 36.

Ihis adjustable stop is adjusted by means of a screw R8 and the spiral ending grooves are for the records which have the uniform stop. Stop R5 requires no adjusting as the eccentric groove IIIA (see Figure 2) when engaged by the needle causes the tone-arm to be swung slightly back or outward. As this occurs the notched edge S2 of plate S (see Figures 5 and 7) engages the stop R5. This rocks shaft R4 forward to withdraw the latch arm R3 and thus releases the lever R so .that the front end of the latter may descend through the force of gravity for the purpose of effecting, through mechanism partly described hereinbefore, counterclockwise movement of the magazine and other operations, which must occur in the interim between sound-reproduction operations. The plate S rotatable horizontally around the axis of movement of the tone. arm, is provided as shown by Figure 26 most clearly, with a depending peg or pin SI, and with peripheral notches S2. There is provided on this plate an ear I05 projecting downwardly which has a hole' drilled through it suitable to allow the adjustable screw V5 to pass through. In this plate is placed in position on said support and the adjusting screw V5 passes through the hole in the bent ear I05. Then the spring V6 is placed around the screw between the ear on the plate S and the threaded ear of the tone-arm support. The purpose of this adjusting screw is to adjust the tone-arm so that the needle will be lowered at a predetermined point on the record when in playing position. After this adjustment has once been made, it is not necessary to be changed unless a sound box carrying the needle in a different position should be substituted. The springv is merely to provide suiiicient frictionfor preventing the adjusting screw from. working loose or moving.

In the frame A, I have provided a suitable support A-III (Figures 3, 4 and 12) which has been bored and faced to support ball bearings,-.not shown. In the upper portion of the frame is secured a flange support A-,-II. The top portion of this support is threaded and provided with a dog nose screw AI2 shown in Fig. 12. As a suspension and swivel support for the swinging tone-arm support V which, on its lower end VI has a short stud 0 suitable to support the same in the ball bearing hereinbefore mentionedas placed in the support A-Ili. This swinging support V, when placed in' its proper position, will swing silently with a minimum amount of friction.

The upper portion of this swinging support is hol- I prefer to have this tail WI on the inside of the swinging tone-arm support (as shown), but when used together with an acoustical horn it is nec essary to have the tail pass through a hole, (not shown) in the back and on the outside of the swinging support. \In' the lower portion of this support V is a spring actuated lever V2 and the upper portion is marked V2. When this lever V2 is pressed down. V3 comes in contact with the tail lever WI on the tone-arm, causing the needle to be lifted off of the record and held in that position while the tone-arm is swung clear of the record and until it has been returned to and lowered upon the next record. In the upper portion of the frame A between the bearings A-Ifl and AI2 (see Figure 12) is a hollow projection which is turned on its outside to fit the large hole in the plate T (Figure 7). Also the plate U (Figure 12) is placed above the plate T so that both plates can be turned a portion of a revolution. On the plate T is an arm having a hole TI by which it is pivoted to 'a rod (see Figures 12, 15 and 38) T2. On the opposite end the shaft T2 has been turned down to a shoulder enabling it to be passed through a knuckle joint 30. Be-

j'tween the shoulder and the knuckle joint 3C is a spring T3, see Fig. 15. At the extreme end is lever is also connected with the lever 3F, which is used in connection with the turning and raising of plate I.

Plate U, mounted to turn in a horizontal plane, has an arm provided with an ear which is bent downward and there are provisions for attaching a retractile spring U3 (Figure 5), secured at its opposite or left-hand end to a fixed stop A9, on the frame A. There is also provided a stop contact UI on plate U, and another projection U2 of said plate comes in contact with the ear I05 on plate S (Figure '7), at the time the tone-arm W is permitted to be pushed to the left by this projection U2 (Figure 5), into a. playing position. In the frame A, is the projection A9 which is used for a permanent stop, see Figure 5, for the plate U and hence of the tone-arm, as hereinafter appears. Above the stop A9 I mount a movable bracket X (F gures 2 and 7), hinged by means of a shoulder screw XI (Figure 8) to a projection or boss on the frame A. One end of this bracket is a movable stop $2. The opposite end is hinged to a rod .13 (Figures 1 and 8). The rod 2:3 is attached to a swinging bracket :04, (Figures 8 and 10), mounted on a horizontal stud :06 which is fastened to the frame A. There is also provided on this bracket a roller :25. The roller 2:5 comes in contact with high and low points on the periphery of cam plate B4 (Figures 8 and 10) which causes the bracket X to move and operate its stop end x2. When the roller :05 comes in contact with a high point on the plate B4, the lever X is moved sufliciently to swing the stop end :2 out ofposition so that it will not come in contact with the point UI on plate U. In that case the spring U3 will draw the plate U forward until it comes in contact with the permanent stop A9. The projection U2 will come in contact with the ear on the plates,

causing the tone-arm to swing the proper distance so that the needle will be lowered at the right Figure 8), contacts with the roller x5 and the spring and will cause the rod $3 to be drawn back (to the left) to its limit so that stop m2 will be in position to contact at U-I with the plate U. Therefore it will cause the tone-arm to be so adjusted that the needle will be-lowered in the proper place to start playing on the large record, see Figure 2.

Referring again to the mechanism for raising the tone-arm and needle, I have provided a cam lever 5A (Figures 7, l8 and 21) to operate in connection with cam 5. The roller on one end 58 comes in contact with cam 5 on the shaft L. Cam bracket 5A is hinged on horizontal shaft 0. Hinged to the outer end of this bracket is a knuckle joint 50 to which is pivoted a rod 5E. One the threaded upper end of this rod 5E is provided an adjusting screw 5D. The lower end of 5E is slotted and hinged to a lever 5F (Figures 1 and 5). The lever 5F is pivoted to a stud 5f onthe frame A, shown in Figs. 3 and 4. One end of the lever 5F is flattened to make a suitable contact on the lever V2 in the swinging tone-arm support. (Figures 5 and- 12.)

In the frame A is mounted the horizontal cam shaft L, and a parallel cam shaft M shown in Figs. '7, 12, 16 and 1'7 and in section in a number of the otherdrawings. These cam shafts L and M are provided each with four keyways milled from the threaded portion-to the opposite end. On the rear-ends of these shafts L and M,

I have securely fastened collars, and the other ends are threaded to receive the nuts LI (Figure 5), and M2 (Figures-16 and 17). Mounted on cam shaft L are cams I, 2, 3, 4, 5, 8 and I numbered progressively frbm'the rear forward. Intermediate between cams 6 and I is mounted a. worm gear J I (Figures '7, 16 and 17). Add these cams as well as the gear Wheel JI have holes broached in them, leaving places to fit the keyways that are milled in the cam shaft. mounted between the cams 2 and 3 is a small spur gear L2 (Figures 16 and 17).

I have provided space collars between each of of the front framesupport for shaft M, are two washers m. There are also spaced collars m between the'cams, gear and washers holding them in their proper places. The collar which is placed on the end of this shaft, and the one that is between the two washers m are journals which fit the bearings in the frame A; The washers are for the purpose of preventing the shaft from moving endwise. They are all, clamped and held in place by the nut M2. 4 n I In the frame A I have'pro ided suitable bear- 'ings'n for a rockshaft N.- (Figures 3, 12 and 20) This shaft is smaller but similar to the cam shaft M, having four keyways' milled in the same and 'ZI is a segmental gear Z2.

threaded at one end. A threaded collar (not shown) is used in this case instead of the hexagon nut. Mounted on this shaft is a handle Q and three plates, with star points provided for" a purpose hereinafter described, numbered N8,

N9, and NI shown in Figs. 7, 12 and 20.

The handle Q and the-three plates have all holes broached in them to fit the four keyways in the shaft N. There are spaced collars provided between the plates and the handle and they are clamped securely by the threaded collar which holds them in their proper places and prevents them from turning on the shaft N. Par-' allel cam lever shafts O and P are mounted in the frame A at opposite sides of shaft N. -Mounted loosely on the shaft are cam levers IA, 2A,

4A, A, and 6A (Figures 12, 16, 1'7 and 20).-

Mounted loosely on the shaft P are cam levers 8A, 9A and 3a. Attached to the cam lever 3:1 by

means of a shoulder rivet is a roller 3b. To one end of the cam lever 3a is attached a spring 200, the other end of which is attached to a hook on the lower portion of the frame A (Figure 18). The cam levers IA, 4A, 8A and 9A are each provided with a hinged joint IC and 9G to which a smallrod is secured as shown in Fig. 12. The other cam brackets do not require adjusting in that way.

In the frame A near the support of the turn table spindle GI, see Fig. 5, are two projections with holes Y6 and 26- to provide bearings for shafts YI and ZI. Mounted securely on me lower portion of the shaft YI is a segmental gear Y2. On the upper portion of this shaft is mounted a lever Y with a finger Y5. Mounted intermediately or between the bearings of the shaft Mounted at the upper end of the shaft ZI is a lever Z (Figure l) with the finger pin Z5. At the extreme lower end of this. shaft mounted securely is a lever 6G. To the lever 6G is connected a rod 6F which rod is hinged to cam lever 6A, as shown in Fig. 1.

On segmental gears Y2 and Z2 are provided projections suitable for attaching a spring Z4. Cam lever 3a is provided with a roller 3b which contacts with the cam 3. .Cam lever 3a-is hinged on.v

the front end of the shaft P, as shown in Figures 15 and 18. Cam lever 3a is for the purpose of pulling the latch end of lever R2 down so that the latch key R3 will engage in the notch R2; (Figure 7.)

I have provided a horizontal plate I, Figures 1 and 15, stamped out of sheet metal and drawn into suitable shape. with the upper portion flanged as indicated at II, to come in contact with the floating disc G3. There is a collar drawn on the lower portion which has six spiral notches milled in the extreme lower part and formingfcams. There is attached to this plate a projecting lever or arm z'-I. The outer end of this lever is hinged to the connecting rod 3F which connecting rod is hinged at the other. end

to the cam lever 3A. On the upperportion of the frame, adjacent to the upper bearings of the turn-table spindle GI,' a projection has been turned to fit the collar portion of the lift-plate I,

which has been turned suitable for the purpose,

I have mounted a collar I--'-3-', which has-six spiral notches milled in the upper portion, as shownv in Fig. 3. The stamping I, with its collar and corresponding notches, fits the notches of i-l causes the lift-plate to turn a sufficient amount and slide upward on the inclines on spi-' ral inclines until the'high points are resting on top of each other. The flange portion I--I comes in contact with the friction disc G2 which is on the under side of floating disc G3 and raises G3 oil of the turn table G about $4,". The floating disc is held in this position while the record is being removed and until the next record is placed in position on top of this disc G3. I have provided in the lift-plate I, means for attaching on opposite sides springs I-2 (Figures 1 and 2) which on their other ends-are attached to projections which are provided for the purpose .on

frame A. It will be seen that these springs are attached in a way so that both are pulling at an angle so that the'lift-plate is rotated backward and downward, and when the cam 3 has rotated far enough to allow thecam lever 3A to be drawn back to its normal position, the lift-plate I will also be forced backward and downward to its normal position, thus lowering the floating disc G3 and its friction disk G2 to contact with the turn table G, and as the turn table G is in continuous motion, the friction is sufficient to cause the floating disc G3 to rotate with the turn table G andthus give proper motion to the record while it is being played. The lift-plate I is caused to move down far enough when in its normal position so that there is about ,4," space between its flange and the floating disc G3; Thismethod of starting and stopping the record's rotation while the same is being transferred to and from the floating disc without its being necessary to stop the turn table G is a novel feature, as suddenly stopping the turn table gear causes a jerk and considerable wear to the gear F3 and is liable to cause unevenness in the teeth which in turn will have a tendency toproduce a waver in the music which the automatic phonograph furnishes.

Mounted on the shaft 0, (Figures 2, 5, 12, 13, 15, 17, 18, 19 and 20) I have provided two latches 0-4 and O9. Mounted on the shorter parallel shaft P, I have provided a latch PI shown in Figures 2, 12 and 20. On the upper portion of the cam lever IA (Figure 20), I have provided two catches or teeth IE. and ID for the purpose of engaging the latch PI when it is released and allowed to drop a sufllcient amount to engage with one notchor the other. In the position shown in Figs. 12 and 20 where the adjusting handle Q is placed in stop notch QI the first or right-hand point on plate NI (Figure 20) comes in contact with the latch PI on shaft P and holds it just high enough so that its catch or tooth misses thecatch ID in the upper portion of cam lever IA, but comes in contact with catch or tooth IE of lever IA. When the adjusting handle Q is placed in the notch Q2 the star point on plate NI on shaft N is rotated far enough to disengage the latch PI and allows it to drop far enough to engage the catch- ID on the upper portion of cam lever' IA. The second star point on the plate NI is longer than the first star point and when the handle Q is moved to the position and engaged in the notch Q3, the second or longer star point raisesthe latch PI high enough so that it does not come in contact with either notch IE or ID on cam lever IA. When the handle Q is moved to the position and engaged in notch Q4, the long star point on plate NI is rotated far enough so that it permits the latch PI to drop low enough again to engage the catch ID in the upper portion of cam lever IA. When this cam lever is latched at ID the spring II is prevented from backing up the ratchet bracket IG therefore nullifying the action of cam lever IA, see Fig. 11. When the latch PI is raised a sufllcient amount to engage the catch 'or tooth IE on the cam lever IA as shown in Figs.

12 and 20, it will permit part action of cam lever IA, causing-the ratchet dog IH (Figure 11) to rotate backward and forward only one notch. When the latch key PI is raised to its full height as when the handle Q is engaged in stop Q3, cam lever IA is allowed to travel its full motion and the ratchet dog IH engages in every other notch of the ratchet plate BI thereby causing the rotation'of the revolving magazine B two spaces at a time. Gain levers 8A and 9A on shaft P (Figures 12,19 and 20) are provided with one projection or catch only, 8E and 9E. The latches O9 and O8 pivoted on shaft 0, are raised and lowered by the various positions of the handle Q, which causes said latches respectively, to nullify the action of cam levers 8A and 9A, or, permits their action as the case may be, but only operates on one notch at a time. When the handle Q is in the po- When handle Q is moved to stop 2, the first or right-hand star point on plate N-8 on shaft N (Figure 20) causes the latch 0 -8 to be lifted and frees the action of cam lever 8A. When the handle Q is moved to stop Qi'the flrststar point has moved sufllciently past the point of contact on latch 0-8 to permit it to fall again so as to engage the catch IE of cam lever 8A thereby again nullifying its action. When the handle Q is moved to stop Q4 the second star point on plate N-O causes the latch O 8 again to be lifted and frees the action of cam lever 8A. In other words, the cam lever 8A is only permitted to have action when the handle Q is placed in stops Q2 and Q4 and in the other two positions its action is, nullified as has been described. When the handle Q is placed in stop QI the latch O-9 is permitted to engage the catch 9E on the cam lever 9A causing its action to be nullified and also when the handle is placed in the stop notches Q2 and Q3. When the handle is moved to stop Q4 the star point on plate 9 engages in the latch 0-9, causing it to be lifted and thereby freeing the action of cam lever 9A. Cam lever 9A is only permitted action when the handle Q is placed in stop Q4. Mounted on the cam shafts L and M are intermittently operated spur gears L2 and MI. (Figures 12, 16 and 17.) The ratio of these gears is one to two. 'As the cam shaft L makes one complete revolution the cam shaft M is only turned a half revolution.

The cams 8 and 9 (Figures 7, 16, 1'7, 19 and 20) mounted on cam shaft M, are double in their action, that is effect two operations in each revolution. With reference to the first half revolution of cam 8, starting from the position shown in the drawings in Fig. 20, it first has a decline 8A, and then has its first rise, which is suflicient to only rotate the revolving magazine counter-clock-
